Right now string theory is just not a TOE, it's just a TOENAIL! Will this always be so? Will string theory ever expand to include a whole TOE? Personally, and from a position of ignorance, I take (the unoriginal) view that a new revolution is needed, and that string is something like Bohr-Sommerfield quantization. If this is true, then: 1) we're missing something big; this notwithstanding, string theory is worth studying. Regards, George PS According to Warren Siegel, a TOENAIL is a Theory of Everything Not Appearing in Laboratories. Saw in this in a comment on Jo Anne JoAnne Hewett's interesesting blog posting, http://cosmicvariance.com/2005/11/18/a-particle-physicists-perspective/#comments", on Cosmic Variance. Dimitri Terryn makes a nice comment.
